STEAM PLOWING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 267,996, dated November 28, 1882.

4 Application tiled July 5, 18H2. (No model.)

To all whom it may concern Be it known that I, NEWTON W. BRADLEY,

'of Ogden, in the countypt' Lenawee and State lowingisa full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beingV had to the accompanying drawings, which form a part ot' this specification. A Y This invention relates to steam plowing apparatus, and has for its object to provide a simple, powerful, andy efficient means for operating the plows.

To this end it consists in certain improvements in the construction and operation of the same.

In the drawings,Figure 1 is a side view of the complete apparatus in operation 5 Fig.2, a top view of the cable-gear; Fig. 3, a sectional view on the line x rv, Fig. l; Fig. 4, a perspective view, illustrating the brake or anchor for securing the engine; and Fig. 5, a side view illustrating a modification in the cable mechanism.

Referring by letter to the drawings, A designates a portable engine, having at its rear end brackets B B, one on each side, and at its front end like brackets, C C. To either pair ot' these brackets can be connected by a pivotjoint two side pieces or beams, D D, having a cross-strip, E, at their bottoms, provided with grab-teeth F, as shown.

To beamsD D are pivoted levers G G, having a connecting axle or shaft, H, journaled at y the bottom of the levers, as at l I, and provided with wheels or rollers J J. The levers G G are normally in an upright position; but by bringing themdown away from the engine the teeth Fwill firmly bind in the ground. Thus the engine may be firmly anchored in place at either end.

The body ot' the engine 'is provided on one side with brackets K K, which support preferably inclined strips L L, forming a rack or bracket, as plainly shown in Fig. 1. Between side pieces L L are journaled a train of gear- P, `slidin g on a transverse shaft, Q, which may be journaled at its inner end in a bracket or carries a band or chain'wheel, S, connected by a drive belt or chain, T, with a band or chain wheel, U, on the drive-shaft of the engine. In

lieu of belt, suitable gear-wheel mechanism may be provided. The clutch P is thrown into and out of engagement with the wheel (l) by means ot' a pivoted operating-lever, V, and motion is thus communicated to drive the train M.

W is the plow, which may be ot' any desired construction, and to its beam is adapted to be secured a cable or drive-chain, X, which is passed through the train M, being passed alternately under one pulley Naud over the next, and is wound a number ot times around' the topmost or last pulley. It then passes under a pulley, Y, which may be arranged onthe front axle of the engine, and its end Z carried forward, the feed being taken up by aman or horse at that end.

The operation and advantages of my invention will be readily understood. The engine remains stationary and draws the plows by the cable. When the latter is all taken in, the engine may be moved forward to pay out the cable and again anchored, the operation and movement being repeated until the full length The clutch P 1 of the field is plowed. Then, instead of having` to turn the engine, the anchor may be shifted to the opposite end and the plows` drawn by a reverse motion ot the engine, as the cable mechanism will operate 'equally as well in either direction. The engine being stationary, its full power is exerted to draw the plow,and no power is lost orexpended to carry the engine. l

Fig. 5 illustrates a modification by which the cable is automatically wound up as it is taken in. In this modification the rack L L is dispensed with, and the gear-wheels thereon are journaled at suitable poin ts on the side ot' the engine, a drum, A', being provided under the latter, round which the end of the cable is adapted to wind. To rotate the drum it may be connected With the pulley on the driveshaft ot' the engine by a band, B', suitable clutch mechanism being employed to throw the drum into and out ot' engagement.

IOO

I claim and desire to secure by Letters Paten t- 1. The combination, with a portable engine adapted to remain stationary during the operation, and provided with a continuous gearwheel and pulley mechanism, of a drag cable or chain adapted to draw the plows by passing over and through the pulleys, being fed out at the forward end and arranged to be paid out at the rear end by releasing the clutch mechanism when the engine moves forward to take another stand, substantially as set forth.

2. The combination, with the engine having a rack or bracket, in which is journaled a train of gear-wheels carrying grooved pulleys or disks, the end one ot'which is connected by a suitable clutch mechanism with a drive-wheel, of the cable or drag chain carrying the plows and passed alternately under and over said pulleys and fed out at the end, substantially leys, and having a pulley, Y, on its front axle under the said train, of the drag cable or chain passing alternately under and over said pulleys and out under pulley Y, substantially as set forth.

4. The combination, with the engine carry- I ing suitable pulleys, through and under and over which passes the drag cable or chain, and having brackets at its end, of the brake or anchor pivoted to the latter, comprising side pieces having a cross-piece at the bottom provided with grab-teeth, and levers lpivoted to the side pieces, and having a cross shaft or axle carrying wheels or rollers, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
